iNaturalist provides suggested language to explain to new users how to fix such problems as multiple species in one observation (obs), failure to tag an obs Captive/cultivated, missing date or location. The URL is https://www.inaturalist.org/pages/responses
It would really help to have a hot link to this page handy when I am using the Identify tab to locate obs that I can ID. Sometimes I end up composing my own instructions rather than looking for the suggested responses page.
Even better would be the ability to type something like “###5a” in a comment box and have the text appear for web users who have multiple species in a single observation.
[And, hey, iNat could even save computer space. If I used the above-mentioned plug-in without modifying it, the text of my comment could be saved as ###5a.
